About this project

The NSW Government is investing $500 million to upgrade the roads around the new Northern Beaches Hospital with work proposed to be completed in time for the hospital opening in 2018.

The upgrades will provide customers with a better travel experience, increased capacity on the road network and improved access through the area, including for pedestrians and cyclists.

Project approvals

The project received planning approval in two stages. The first stage to improve connectivity to the new hospital and carry out early preparation work for the road upgrade was received on 29 June 2015. Planning approval for the final stage to enhance the local road network was approved on 25 February 2016.

Key features

Forest Way and Frenchs Forest Road

New traffic lights with signalised pedestrian crossings at the intersections of:

Forest Way and Naree Road

Naree Road, Rabbett Street and Frenchs Forest Road West

Frenchs Forest Road West and the new access to the hospital opposite Gladys Avenue

Improvements to the intersection at Frenchs Forest Road East and Nandi Avenue, allowing left and right turns

Warringah Road

Providing four through lanes on Warringah Road (two lanes in each direction) within a grade separated underpass (open slot) for about 1.3 kilometres. The underpass would be below ground level and below the intersections with Forest Way, Hilmer Street and Wakehurst Parkway

Providing a two-lane on-ramp (merging into one lane) from Wakehurst Parkway (southbound) into the underpass (westbound).

Upgrading surface-level lanes along Warringah Road on either side of the underpass

Traffic using the Warringah Road underpass would travel below the intersections with Forest Way, Hilmer Street and Wakehurst Parkway. These intersections would form a surface level bridge for local access
